Oil leak found in southwest Ohio nature preserve

CINCINNATI — A spokesman for the company that is the main owner of a pipeline that leaked oil in the area of a southwest Ohio nature preserve says an estimated 240 barrels were released.

The Mid-Valley Pipeline Co. pipeline runs nearly 1,000 miles from Texas to Michigan and is largely owned by Sunoco Logistics. A Sunoco spokesman says the cause of the leak is under investigation.

Authorities say the pipeline has been shut off and the leak contained. An Ohio Environmental Protection Agency spokeswoman says a wetland of about one acre was affected by oil that went about a mile down an intermittent stream.
